Abstract

PURPOSE:To increase the sentitivity of radio receiver, by connecting one end of the coil to the antenna and grounding another end through the winding of the coil on the bar antenna. CONSTITUTION:The resonant frequency of the bar antenna constituted that the coils 4 and 5 are wound on the rod iron core, is made in agreement with the input signal frequency, and the coils 7 and 7' are wound on the bar antenna, and the end of the coil 7' is used for the antenna and the end of the coil 7'' is for grounding. Thus, the sensitivity of radio receivers can be increased.
